MTS out of substrate
I have MTS in all of my planted tanks. They don't bother me because I don't see them much on the glass during the day. When they do come out, I vacuum the substrate and do a larger water change.
Sometimes I see them out when I feed my fish shrimps, other times is when I fertilize micro nutrients (I know they don't appreciate the copper..). But once in a while, they are all over the glass, in large numbers, racing to reach the surface, with no apparent reason.
Any idea what are they indicating?
